WebSep 1, 2000 · Fourth-order tensors as a mathematical object have found in the last 20 years a wide use in computational mechanics and especially in the finite element method. Their well-known applications are tangent (elastic or elasto-plastic) moduli as well as damage tensors playing an important role in the formulation of constitutive and evolution … WebJul 30, 2024 · A tensor of fourth order is a way of representing an arbitrary linear transform on this vector space of matrices. On the other hand, multiplication by a matrix represents a more specific type of linear transformation on the vector space of matrices.
